After the installation of MySQL server or MariaDB on Ubuntu, I would like to use phpMyAdmin or Adminer to access the MySQL server. But the first time the error comes like below.
Access denied for user ‘root’@’localhost’
mysqli_real_connect(): (HY000/1698): Access denied for user ‘root’@’localhost’
MySQL connect error on phpMyAdmin
MySQL connect error on Adminer
Here is the solution to make the root connect to a server without error.
